Bug#508971: gdm: fails when a user has logged out and as other are still connected

[Denis Laxalde]

Package: gdm
Version: 2.20.7-4
Severity: important

When several users are connected in gnome (through the multi-user
functionality) and when one of them logs out a repeated system bip
occurs.
Then, when an other user tries to log out or switch to another user,
gdm crashes with a black screen !
The only way I found to recover is to kill the gdm process.
Since, I experienced this in Debian sid and lenny and previously in ubuntu 8.04.1 the bug might be reported upstream.
Thanks!
